You want a flimsy shell and to externalise the environmental impact? Sure thing, whatever the market will bear and is legal.
I think it is fair enough for people to put pressure on current practices. Zara and H&M will persist, but their customers should be and, thanks to outside voices, are now aware that social and environmental factors are involved in fast fashion.
Sure, it's arbitrary. But we still have alternatives. All else being equal, less entropy is better than more.
